PENClL-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 755,917, dated March29, 1904.

Application filed December 15, 1903. Serial No. 185,224. (No model.)

To all whom it may concern:

Be it known that I, EDWARD L. MODIVITT, a

citizen of the United States, residing at Belvidere, in the, county ofBoone and State of Illinois, have invented certain new and usefulImprovements in Pencil-Sharpeners, of which the following is aspecification.

The object of this invention is to construct a pencil-sharpener in whicha knife is supported by a swinging arm which moves in contact with aninclined guide-post and a support for the pencil, thereby whittling theend of the pencil to a point, and in the knife made movable in itslengthwise direction, so that new wearing-surfaces may be presented. 7

In the accompanying drawings, Figure 1 is a plan View of my improvedpencil-sharpener. Fig. 3 is an end elevation. at, Fig. 1.

The base portion 1 forms a receptacle for holding the whittlings and inthis instance is cylindrical in form and supported upon the rubber tips2.

Within the base is located an incline 3. To the side of the incline issecured a holder or guide 1 for the end of the pencil. A support for thepencil islocated in rear of the'holder 4 and comprises the forked upperend 5 and screw-threaded shank 6, having a connection with the boss 7,extending from the bottom of the base.

An arm 8 has two perforated ears 9 at one end, a handle 10 at its otherend, two projections 11 extending from its lower face, and a lug 12extending from its upper face and provided with a screw-threadedopening. A screw 13 has a connection with the lug 12. The upper innerfaces of the projections 11 are recessed. A knife-blade M has itsbeveled lower edge located in the recesses of the projections, and thescrew 13 is turned down against the upper edge of the knife, therebyholding it in connection with the arm 8 in a manner to permit it to beadjusted in the direction of its length in order that nearly the entirecutting edge may be'used.

Between the ears 9 is located an eye 15, having a screw-threaded shank16. This shank Fig. 4c is a section on dotted line has a screw-threadconnection with the boss 17 extending diagonally from thebase. The shank16 is located at substantially right angles to the incline 3.

In use the end of the pencil to be sharpened is located in the holder 4:and in the support 5 and constantly turned while being sharpened. Thearm 8 is given a swinging movementup and down the incline, which willcarry the knife in contact with the end of the pencil, thereby removinga portion of it, which is repeated as the pencil is turned. The ofiset18, extending from the rear upper edge of the arm 8, serves to hold theupper edge of the arm some distance from the incline, thereby presentingthe knife diagonally to the lengthwise direction of the pencil. Byrevolving the arm 8 the shank 16 may be lengthened, which will lessenthe cut of the knife. The arm could not be revolved were it not for itspivotal connection with the eye 15. By adjusting the pencil-supportvertically more or less pitch is given to the pencil with respect to theknife.

I claim as my invention- 1. A pencil-sharpener comprising areceptacle-base, an incline supported by the base, a pencil-holder, apencil-support, anda knife having a swinging movement over the holder,and guided by the incline.

2. A pencil-sharpener comprising a receptacle-base, an incline supportedby the base, a pencil-holder, an adjustable pencil-support, and a knifehaving a swinging movement over the holder and guided by the incline.

3. A pencil-sharpener comprising a receptacle-base, an incline supportedby the base, a pencil-holder, an adjustable pencil-support, an armhaving a swinging and pivotal movement, and a knife supported by thearm.

4. A pencil-sharpener comprising a receptacle-base, an incline supportedby the base, a pencil-holder, an arm having a swinging movement over theholder and guided by the incline, and an adjustable knife carried by thearm.

5. A pencil-sharpener comprising a receptacle-base, an incline supportedby the base, a pencil-holder, an arm having a swinging and pivotalmovement, a knife carried by the arm,

the projections and made movable in the I lengthwise direction of thearm, and a screw i'or clamping the knife in engagement with theprojections.
